[s-cars] Re: Auxiliary Coolant Pump Bosch P/N

Bob,

Yes, I believe the Bosch 392 020 054 p/n is accurate.  I also just changed
that part on my '92 S4, it was also beginning to drain a little coolant from
one of its hose fittings.  Sure enough the hose fitting was broken inside
the hose (under the clamp).  I went to a generic Bosch supplier and paid
$171 (CDN) as apposed to the $369 that the dealer wanted!!!  It was also a
very easy installation. 10 minutes.  Just remove the 2 hose clamps and
disconnect the hoses, then unclip the electrical connector and slide the old
pump out from the 2 rubber donuts that are holding it in-place.  Then
re-insert the new pump back in and reconnect the hoses and the electrical
and voila, your done!  Remember to have a catch pan under your car... you
will loose about 2 liters of coolant in the process.
